Abstract: Provided in the present disclosure are a display panel and a manufacturing method therefor, and a display apparatus. A pixel defining layer includes a plurality of first barrier walls and a plurality of second barrier walls, which are arranged in an intersecting manner, where a height of the first barrier wall is smaller than a height of the second barrier wall, and orthographic projections of via holes for connecting light emitting devices on a base substrate are located in orthographic projections of the second barrier walls on the base substrate. Due to a great thickness of the second barrier walls, an effect of covering via holes can be better by providing the via holes below the second barrier walls.
